The Adventures of Captain Horn by Frank R. Stockton

Early in the spring of the year 1884 the three-masted schooner _Castor_, from San Francisco to Valparaiso, was struck by a tornado off the coast of Peru. The storm, which rose with frightful suddenness, was of short duration, but it left the _Castor_ a helpless wreck. Her masts had snapped off and gone overboard, her rudder-post had been shattered by falling wreckage, and she was rolling in the trough of the sea, with her floating masts and spars thumping and bumping her sides.

The _Castor_ was an American merchant-vessel, commanded by Captain Philip Horn, an experienced navigator of about thirty-five years of age. Besides a valuable cargo, she carried three passengers -- two ladies and a boy. One of these, Mrs. William Cliff, a lady past middle age, was going to Valparaiso to settle some business affairs of her late husband, a New England merchant. The other lady was Miss Edna Markham, a school-teacher who had just passed her twenty-fifth year, although she looked older. She was on her way to Valparaiso to take an important position in an American seminary. Ralph, a boy of fifteen, was her brother, and she was taking him with her simply because she did not want to leave him alone in San Francisco. These two had no near relations, and the education of the brother depended upon the exertions of the sister.
